Description
Summary:We carry out necessary theoretical justifications for the method of recoil nuclei in application to the direct observation of the 229mTh isomeric state. We consider Cherenkov radiation, phosphorescence, and fluorescence in a crystal plate, which is used for collecting the thorium recoil nuclei, and discuss the ways to avoid these parasitic signals in order to successfully reveal 229mTh decay photons.
